Django Trick: Using bulk_create for Efficient Bulk Inserts

When inserting multiple records into the database, using the bulk_create method can significantly improve performance compared to inserting records one by one. While many developers are aware of this feature, fewer know about its flexibility and how to utilize it effectively, including handling defaults and signals.

How It Works: The bulk_create method allows you to create multiple instances of a model in a single query, which reduces the overhead of individual inserts. You can also handle defaults and manage large datasets more efficiently.

Why It’s Cool: Using bulk_create can drastically reduce the number of database queries, making your application more efficient, especially when dealing with large datasets. It’s a simple way to improve performance during mass data import or initialization tasks.
